1. Identify the Source: Pinpoint the offending bearing with a stethoscope or by jacking up the vehicle and spinning the wheels. | Ignoring Warning Signs: Ignoring the early warning signs, such as a faint squeal or grinding noise, can lead to catastrophic failure.
2. Replace in Pairs: Even if only one bearing is squealing, replace both bearings on the same axle simultaneously. | DIY Repairs: Wheel bearing replacement requires specialized tools and expertise. Leave it to the professionals.
3. Use High-Quality Bearings: Invest in high-quality, aftermarket bearings from reputable manufacturers. | Using Substandard Parts: Cheap bearings may not meet OEM specifications and can lead to premature failure.

1. Safety First: Park the vehicle on level ground and engage the parking brake. | Wheel Bearing Access: Depending on the vehicle make and model, accessing the wheel bearings may require removing the brakes and suspension components.
2. Thorough Inspection: Inspect the bearing for any visible damage, such as cracks, pitting, or corrosion. | Misdiagnosis: Mistaking wheel bearing squeal for other noises, such as brake pads or tires, can lead to incorrect repairs.
3. Proper Lubrication: Apply high-temperature bearing grease to the new bearings to ensure optimal performance. | Overtightening: Overtightening the axle nut can damage the bearing or the axle.
